Active water sampling
When choosing the proper water sampling you have to consider the following parameters:
– volume of the sample (500 ml – 30 l)
– sample matrix
– type of analysis (microbiology – if the sterilization of the vessel is possible? heavy metals – if the sampling system is all-plastic?)
– the depth of the sampling
– the location of sampling system (vertical or horizontal)
– the width of the sampled object (e.g. sampling from the tubes)
– it is required to have a transparent sampling container?
– what kind of analysis will be provided (quantitative or qualitative?)
Several basic types of samplers can be found in the leaflet “Water sampling – Hydrobios”.
More information can be found in the catalog of “Sampling devices – Hydrobios” or contact us via email.
The offer of bottles for water samples you can find in the section “Laboratory consumables”.

– Metals and nonmetals
Basic overview of passive samplers can be found in the leaflet “Passive samplers – Exposmeter”.
